I dont really have one specific favourite Character in anime, but overall Zack Fair/Cloud Strife might be my favourite Characters.

Concerning Anime it might be kinda mainstream but luffy from one piece is my favourite i guess. its not that i think that he is the most badass, the funniest, the coolest, or whatever guy, its just that one piece was one of the first anime i watched, i still was a child back then. i grew up with one piece, and i have watched every single episode and movie over and over. i practically know everything about one piece. thats why One Piece and Luffy are part of my life, and i chose him as my favourite.

There a a few other that i consider my favourite Anime-Characters, but no one is as important to me as Luffy.
